Abstract
The study was undertaken for three primary reasons. First, large areas of the state do not have satisfactory sand and gravel aggregates within economical hauling distance and many of the better deposits in other areas are rapidly becoming depleted. Second, the reduced dead load in lightweight concrete structures makes it very desirable to make more general use of this material. The third reason is that the more advanced design principles adopted in the recent past and those that will be adopted in the future demand a thorough knowledge of the properties of the material to be used. This report presents the results of the investigation.|The body of this report presents figures (illustrations), tables, and discussions which represent the conclusions based on the comprehensive study involving 28 batches of concrete with approximately 437 creep specimens, 160 shrinkage specimens, and 1540 specimens for determining compressive strength, modulus of rupture and modulus of elasticity. This is further supplemented by data taken from a full scale prefabricated, prestressed concrete test bridge built in conjunction with the project. The detailed data concerning the compressive strengths moduli of rupture, and moduli of elasticity are presented in the appendix. The work on the physical properties of the hardened concrete was preceded by investigations involving several hundred specimens on problems of workability, field practice, etc.
